After nearly two weeks of benchmarking, here is a look at our most extensive Linux x86_64 compiler comparison yet between the latest stable and development releases of the GCC and LLVM Clang C/C++ compilers. Tested with GCC 8, GCC 9.0.1 development, LLVM Clang 7.0.1, and LLVM Clang 8.0 SVN were tests on 12 distinct 64-bit systems and a total of 62 benchmarks run on each system with each of the four compilers… Here’s a look at this massive data set for seeing the current GCC vs. Clang performance.
